It is also possible to send paper sizes that do not meet the standards of the TT recommendations.

Note that it is assumed that the receiving terminal is also provided with a table similar to the document size table 100 of this device 1, so that the RDCLP
It becomes possible to set a paper size inside the printer, and non-standard paper sizes may be received.

As described above, according to this embodiment, even if the paper size of the document does not meet the standards recommended by the CCITT, all information on the document can be reliably transmitted without being omitted.

Now, in the above embodiment, the case where negotiation is possible between the sending terminal and the receiving terminal even if it is not stipulated in the CCITT recommendation was explained. A case where this is not possible will be explained as another example.

First, because it is not stipulated in the CCITT Recommendation,
If negotiation is not possible between the sending terminal and the receiving terminal, there is a possibility that the receiving terminal will not be able to compensate for the operation when it receives a control signal such as CDCL for a paper size of a non-standard original. Gender arises. Considering such a case, it is better to use the non-standard terminal functions and usage parameters in CCITT Recommendation T.62 to negotiate non-standard operations between the terminals, and the method will be described below.

FIG. 5 is a diagram illustrating negotiation between a transmitting terminal and a receiving terminal according to another embodiment.

In FIG. 5, CS S (command 5es

Each NSC (non 5tand) in SS and R35P
ard capability) indicates a command that conveys non-standard terminal capabilities; during negotiation,
By using the NSC, mutual functions will be confirmed.

Therefore, in order to perform negotiation, a C8S command is first transmitted from the sending terminal to the receiving terminal, and in response, the receiving terminal sends R3 to the sending terminal.
Transmits 5P commands and responds. Here, non-standard terminal functionality is checked. From then on, as in the previous embodiment, CDCL, R
DCLP, CDS, and CDUI commands are transmitted.

In this way, in the transmission of image data when the CCITT recommendation does not specify the paper size of a document such as legal paper or leisure paper, the other embodiments described above have the same effect as the embodiment described above.・It is possible to not only obtain effects but also ensure reliable operation.

[Effects of the Invention] As described above, according to the present invention, even if the paper size of the manuscript does not meet the standards recommended by the CCITT, all information on the manuscript can be reliably transmitted without being lost.
